Rocks and other hard surfaces here were encrusted with beautiful sea fans and colourful sponges.
Candelabra sea fans and dark red Gnarled sea fans, which are commonly seen on Changi, I also saw some other sea fans which I don't come across very often, like one with a maze-like pattern of branches and a yellowish one.
resemble asparagus, and a white one that looks like a lyre.But I didn't come across large colonies of Skinny sea fans.
Knobbly soft coral (Carijoa sp.) on one. Other animals found on sea fans include Winged oysters (Family Pteriidae), tiny Red ovulid snails and lots and lots of Colourful tiny brittle stars (Ophiothela danae) wrapped around the sea fan branches.
egg capsules on sea fans. The egg capsule is black until the babies are ready to hatch, whereupon they become transparent and we can see the baby moving about inside the capsule!
Zebra corals (Oulastrea crispata), which are common on Changi, there were also those with hexagonal corallites.
Cave corals (Tubastrea sp.).
octopuses which I usually see in reefy areas.
seahorse (Hippocampus sp.)! My first sighting for the year at Changi.
Brown moray eel (Uropterygius concolor)! I've only seen this eel at Tuas many years ago, where there is also a lovely sea fan garden. Although it was out of water, it was very much alive.
Ategema spongiosa. Probably there were lots more which I just couldn't see. Chay Hoon of course found lots of interesting nudis on the other side of the shore.
Pseudoceros laingensis, while the team saw another one on the other side of the shore. Are they seasonally common?
Thumbs up ascidians (Polycarpa sp.). I'm not sure what it is. Some kind of sponge crab (Family Dromiidae)?
sponges on the rocky area, as well as colourful ascidians.
swimming crabs (Family Portunidae). I also saw some Stinging hydroids, small clumps of zoanthids (Zoanthus sp.). Strangely, I didn't come across any feather stars (Order Crinodea).
since 2009. Kok Sheng had a much better look at the area in 2009.
scallops (Family Pectiniidae). These clams have lots and lots of tiny eyes!
Sea lettuce (Ulva sp.) on the shore and on some parts were blanketed by nest mussels (Musculista senhousia).
Hairy spoon seagrass (Halophila decipiens). Recently, we've been seeing these at Changi and at Punggol. Hope we can sort this out eventually.
Jan 2012 when the tide wasn't very low. There sure is a lot of fascinating marine life hidden in our murky waters!
